A second man has been arrested in connection with an alleged plot to try to kidnap, rape and kill an unidentified woman in Manhattan.

Michael Vanhise, 22, of New Jersey, was arrested on Friday and has been charged with conspiring with a New York City police officer in the cannibal plot, according to federal court papers unsealed on Friday.

The FBI says Vanhise agreed last year to pay $5,000 to NYPD Officer Gilberto Valle for the abduction.

Vanhise also admitted emailing other people about kidnapping, raping and killing women and children, according to the FBI.

US Attorney Preet Bharara said Vanhise engaged in conduct "that reads like a script for a bad horror film."

He said the arrest was the second "in this bone-chilling case, but we are not finished."

According to court papers that included transcripts of online chats, Vanhise and Valle conspired to stuff a woman into a large suitcase and deliver her to Vanhise's home. Valle insisted she would still be alive, so that Vanhise could rape her.

The court papers said Vanhise also emailed photographs of a girl whom he knew well after other unidentified co-conspirators expressed interest in kidnapping the child.

Vanhise was charged with one count of conspiracy to commit kidnapping, which carries a maximum sentence of life in prison.

Valle, 28, was charged last year with targeting victims through a law-enforcement database. He allegedly wanted to kidnap, rape, kill and eat women.

He is being held without bail awaiting trial.

A search of Valle's computer found he had created records of at least 100 women with their names, addresses and photos, a criminal complaint said.

In one online exchange in July, Valle allegedly wrote: "I was thinking of tying her body on to some kind of apparatus... cook her over low heat, keep her alive as long as possible."

In other online conversations, investigators said he talked about the mechanics of fitting a woman's body into an oven, claimed he could make chloroform at home to knock a woman out and discussed how "tasty" one woman looked.

Valle's lawyer says he was engaging in sexual fantasies and intended no violence.
